The invention relates tonew and improved means for arranging glass articles ona conveyer, while they are being carried from the forming machine to the leer, so that the articles will be properly spaced for delivery to the leer.

More particularly, the invention relates to means for simultaneously delivering two glass articles to a rotating conveyer, improperly spaced for delivery to a leer, and rearranging the articles, during-the continued rotation of the conveyer, to form a continuous series of articles properly spaced for delivery to a leer.

.The invention will be clearly understood from the following detailed description, when taken in connection with the accompanyingdrawing,

'in which,

The figure is a perspective view of the'com plete apparatus.

Referring now to the drawing, numeral 'l indicates a table which is preferably rotated continuously at the proper speed and in the direction shown'by 'thearrow, by any desired means, and is arranged in front of a leer 2, in which the glass articles are to be annealed.

Numeral 3 refers to two take-out devices which simultaneously remove two glass articles, such as the jars 4, from two molds of a glass-forming machine, and place the articles'on the rotating table I Take-out devices are well known in the art, and as the present invention is not limited to I any particular type of take-out, a description thereof is not necessary. The glass articles, when placed on the table I, are necessarily rather wide 1y spaced due to the spacing of the molds, etc.,

and in order to suitably arranged the articles in rows in the leer, they must be brought much closer together before they are carried into position in front of the leer 2 and delivered thereto by the periodically reciprocated pusher bar 5 or by any other type of leer loader.

Numeral 6 indicates a cylinder mounted on a plate I carried by a. bracket 8. Slots 9 in the cylinder base plate provide means for adjusting the cylinder forward or backward.

The piston rod of the cylinder 6 is indicated by numeral I0, and attached to this piston rod is a bracket II. The bracket carries angularl arranged fingers I2, which constitute a pusher member. When the piston rod I0 is in its rearward position, the fingers l2 are so placed that the rearward of the two jars being delivered to the table will be directly in front of the fingers and adjacent thereto.

The means for operating the cylinder 6 will now be described. Numeral I3 refers to a line (not shown) in the valve, which communicates pressure to a valve I4, and from this valve lines I5 and I6 lead to the front and rear ends, respectively, of the cylinder. A volume control valve I1 is preferably provided in the line l3, and bY-pass valves l8 are preferably provided in the lines I5 and I6 leading to the cylinder. When air under pressure is being supplied through one of the lines to one end of the cylinder, 'airpressure is being drawn from the other end of the cylinder through the other line, and is exhausted to the atmosphere through an opening (not shown) in the valve l4. 7

Numeral I9 refers to the valve stem of the valve I4, and this stem is urged outwardly by a coil spring 20. The valve is mounted on a plate 2| which is supported by a bracket 22. An upwardly extending shaft 23 passes loosely through the .bracket and plate, and carries'at its upper end a cam 24. In the particular form illustrated the shaft 23 is continuously rotated, in the direction indicated by the arrow, by means of a sprocket chain 25 connecting a sprocket on the shaft of an ordinary timer 26, which controls the operations of the glass forming machine and'the take-out devices, with a sprocket on the shaft 23. But,

of course, any other desired means may be employed for rotating the shaft, 7

The plate 2| is pivotally adjusted about the shaft 23, and is held in adjusted position by a slot and bolt connection 21. Numeral 28 refers to an armwhich is pivotally mounted on the plate 2l, and its free end is in contact with the cam 24 and with the end of the valve stem I9.

Thus the continued rotation of the cam will cause the valve stem to be moved periodically to the left to open communication between the line I3 and the line I6 leading to the rear end of the cylinder 6, to admit air under pressure to that end of the cylinder, and at the same time exhaust the air from the opposite end of the cylinder through the line I5 and the opening with the atmosphere. As the rotation of the cam 24 continues, the spring 20 moves the valve stem to the right, thereby admitting air pressure to the forward end of the cylinder and exhausting air from the rear end of the cylinder. By adjusting the by-pass valves I8, the exhaust from either end of the cylinder can be controlled, thereby controlling the rapidity of movement of the piston rod II) which operates the pusher member I2. By pivotally adjusting the plate 2| about the shaft 23, the operator can vary the 2. The two jars last delivered are shown in heavier lines and are referred to by letters A and B, and the two jars delivered to the tabl by the 7 previous operation of the take-out devices, are referred to by Letters C and D. When the articles are delivered, air is admitted to the rear end of the cylinder 6 to move the pusher l2 forward, and thereby move the jar B forward relative to the table I, while all of the jars are continuously being carried forward with the table.

This jar B is not moved forward to a position adjacent the jar D which was delivered in the previous operation, but is only moved forward sufficiently to leave. a space large enough for the placing of another jar between D and B upon the next delivery of two jars by the take-out devices. In other words, the jar B will be moved forward so that it is spaced from D about the same distance that is shown between the jars C and D, and when the take-out devices next operate, the forward jar will be placed between the jars D and 'B, and the rearward jar will be placed rearwardly of the jar B, ready to be moved forward by the pusher l2.

By this simple mechanism it is possible to si multaneously deliver to a rotating table two glass articles improperly spaced for delivery to a leer,

Having fully described the invention, what I claim is:

1. A device of the character described, including a rotatable table, periodically operated means for placing two glass articles on the ta-.

ble in widely spaced relation, means for periodically advancing the rearward of said articles toward the forward article and leaving sufiicient space for the interposition of another article upon the next operation of the placing means, to form a series of closely spaced articles.

2. A device of the character described, including a continuously rotating table, periodically operated means for placing two glass articles on' the table in widely spaced relation, and means periodically operated While the articles are being carried forward by the table to advance the rearward article and leaving sufficient space for the interposition of another article upon the next operation of the placing means, to form a series of closely spaced articles.

3. A device of the character described, including a continuously rotating table, periodically operated means for placing two glass articles on the table, improperly spaced for delivery to a leer, and periodically operated means for varying the space between the articles to permit the interposition of another article, to form a series of articles properly spaced fordelivery to a leer.

4. A device of the character described, including a continuously rotating table, periodically operated means for placing two glass articles on the table in widely spaced relation, a pusher member adjacent the rearward of the two articles, and means for periodically moving the pusher member forward to advance the rearward article toward the forward article and leaving suificient space for the interposition of another article upon the next operation of the placing means, to form a series of closely spaced articles.
